Asymmetric Key (Public Key)<p>Public-key cryptography, or asymmetric cryptography, is any cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner. This accomplishes two functions: authentication, where the public key verifies that a holder of the paired private key sent the message, and encryption, where only the paired private key holder can decrypt the message encrypted with the public key.</p> <p>See also: <a href="https://en.wikipedia.org/wiki/Public-key_cryptography">Public Key</a></p>
